	So this section of man usbd (the first paragraph) needs a rewrite ?

     The usbd utility handles USB device attachment and detachment.  It does
     two things.  Through opening the /dev/usb0, /dev/usb1, etc. devices, it
     enables the kernel to handle change requests from attached hubs.  This
     functionality will be removed when the kernel has kernel threads.  The
     (multiple) -f device command line options specify which controllers it
     should handle.  Normally this option is not needed.

	Or does that refer to something other than attaching devices to
their nodes ?
